Startrails Looking North From My Backyard in New Jersey. Composite of 400 images taken with a Fuji X-T1 camera and 14 mm f/2.8 lens (ISO 200, 14 mm, f/2.8, 30 sec). Raw images processed with Capture One Pro and Photoshop CC. In the past I used the startrails.exe program to create the composite image. This time I made the composite using Scripts/Statistics Stack Mode = Maximum within Photoshop CC 2015.

I am a scientist by training (Eckerd College, BSc; Caltech, Ph.D.). I worked for 27 years as a Chemist in the Pharmaceutical Industry developing processes to manufacture medicines for human and animal health. I now spend my time as a photographer and world traveler. My interests include the natural world, wildlife, landscapes, sky, and seascapes, travel, and astrophotography. I look for unique ways of viewing the world and presenting my images. I have traveled to over 55 countries in six continents, often on Semester at Sea voyages. While at home in New Jersey, I spend time on home renovation and expansion of a wildflower garden/meadow.

Great capture. I'll try that. Did you automate the shutter? How much time between shots? Surprisingly little light pollution. Don't have any neighbors?

+John Hockridge I used the in camera intervalometer set to 35 seconds for 30 second exposures. The extra 5 seconds allows the image to be transferred to the memory card. Three seconds was not long enough (probably depends on the speed of the memory card). If I used an external intervalometer I would go for a 60 second exposure. Much more than that you need to deal with sensor noise. I originally did star trails with very long exposures, but find that doing composites is more reliable and I don't have to do the long exposure noise reduction.
Regarding light pollution, these images were taken between midnight and 4 AM. It was a really clear night so I didn't have much reflection from dust or moisture. Looking south I have to deal with the lights in Princeton and Trenton.
+Joan Mathre I suspected that in the past, but a tree next to the house partially blocked the North Star. Now that the tree is gone it is evident that the North Star is a bit off from the true astro North point.
Great!
Amazing Photo
wow
Cool!

I now see clearly that the rotation is not around the North Star…just a bit off.

whaaaaaaaa,, AMAZING
